Contract Management for Oil and Gas (2026)

What contract management means in oil and gas Oil and gas is one of the most contract-intensive industries there is. A single asset can run on a production sharing or revenue sharing contract with the state, joint operating agreements between partners, drilling and oilfield services contracts, long-term supply and offtake agreements, transportation and pipeline contracts, and a dense layer of health, safety and environmental obligations. The values are large, the terms run for years or decades, and the regulatory and environmental exposure is heavy. Contract management is the discipline of keeping this estate drafted, reviewed, signed, stored and tracked against its obligations, prices, volumes and compliance deadlines. The short answer: good contract management in oil and gas means the master agreements (the licence or sharing contract, the joint operating agreement, the key supply and offtake deals) and their many subordinate contracts are controlled and linked, liability and indemnity are allocated clearly across a high-hazard chain, and every obligation (minimum work programme, royalty and payment dates, HSE compliance, insurance, decommissioning) is a dated reminder owned by someone. ## The contracts the industry relies on - Upstream and licensing. Production sharing or revenue sharing contracts with the government, petroleum exploration licences, joint operating agreements (JOA), farm-in and farm-out agreements, and unitisation agreements.

• Services and drilling. Drilling contracts, oilfield services contracts, equipment hire and supply, engineering, procurement and construction (EPC) contracts, and master service agreements with day-rate and risk-allocation terms.
• Midstream and transport. Pipeline transportation agreements, gas transmission and capacity contracts, storage, and shipping and charter arrangements for crude and LNG.
• Downstream and offtake. Crude and product sale and purchase agreements, long-term gas supply and offtake agreements, refining and processing contracts, and distribution and retail dealer agreements.
• Compliance and closure. Health, safety and environment obligations, insurance and liability arrangements, and decommissioning and abandonment agreements. ## The risks that matter most Liability and indemnity allocation. Oilfield operations are high-hazard. Services and drilling contracts typically use a knock-for-knock liability structure, where each party bears its own people and property losses regardless of fault, backed by indemnities and insurance. Getting this structure right, and matching it to insurance, is the central risk. Minimum work and payment obligations. A sharing contract carries a minimum work programme, exploration commitments, royalties, profit-share mechanics and strict reporting to the regulator. Missing a committed well or a payment date has consequences that run to the licence itself. Price, volume and take-or-pay. Long-term supply, offtake and transportation contracts carry price-review formulas, take-or-pay obligations, and volume flexibility. These need precise drafting and tracking because the sums are large and the terms run for years. HSE and environmental exposure. Environmental clearances, spill liability and emissions obligations flow into contracts and into the operator's own compliance calendar. A missed clearance or lapsed condition can halt operations. Decommissioning. End-of-life obligations and the funding for them are contractual and regulatory. They must be provided for from the start, not discovered at the end. ## The workflow, stage by stage 1. Request and draft. Start from the approved master or model template. Many upstream contracts follow a government model (for example a model revenue sharing contract); services contracts follow an industry master form.

2. Review. Check each draft against your standard positions: liability and indemnity structure, insurance alignment, price and volume mechanics, work and payment commitments, and HSE and environmental obligations.
3. Approve and sign. Route by value and type, record approvals, and use e-signing where valid. Link each call-off, work order or amendment back to its master agreement.
4. Store. Hold the master agreement with every JOA, amendment, work order and annexure together in one place, linked to the asset or licence. The current, complete set should be producible for a regulator, a partner audit or a dispute.
5. Track and renew. Turn obligations into alerts: minimum work milestones, royalty and payment dates, regulatory and reporting deadlines, environmental-clearance conditions, insurance renewal, take-or-pay reconciliation, and decommissioning provisions. Assign each to an owner. ## Jurisdiction notes This page is global with an India-first lens. In India the Directorate General of Hydrocarbons and the Petroleum and Natural Gas Regulatory Board oversee upstream and midstream activity, and model contract forms apply to many licences. Internationally, the industry uses widely recognised model forms and a shared knock-for-knock liability culture, but the host-government terms, tax and environmental regimes differ sharply by country, and many contracts are governed by English law with arbitration. For any cross-border asset, draft with the host-country regime and the chosen governing law in mind. This page is general information and not legal advice. ## Common mistakes Liability and indemnity structures that do not match the insurance behind them. Work-programme and payment commitments tracked informally until a deadline is missed. Take-or-pay and price-review terms that are not reconciled, so money is left on the table or overpaid. Environmental-clearance conditions treated as a one-time approval rather than ongoing obligations. Decommissioning liability not provided for from the start. Master agreements, JOAs and work orders scattered so the full picture of an asset's obligations is never visible in one place. ## One workspace to draft, review and track your contracts Most oil and gas operators do not lose on a single clause. They lose because a single asset's contracts, from the sharing contract down to each work order, live in different systems, the liability and work-programme obligations sit in a few specialists' heads, and the next committed milestone hides in a spreadsheet. The alternative is to keep drafting, review, tracking and governance in one place rather than across five disconnected tools. The idea is simple. You draft from your own catalogue and house style, the system reads any agreement and flags positions as favourable, neutral or unfavourable to you and surfaces compliance items, every edit is tracked on a timeline, and obligations and dates (work milestones, payments, clearances, renewals) become alerts you can assign. Because the contract is held as a structured clause tree rather than flat text, you can change a clause in plain English and see exactly what moved. Adira is one such workspace, built on Anthropic's Claude and tuned to how your company contracts. India is deepest today, with other jurisdictions and a company command centre on the roadmap.
